Description
- 1. Field of the Invention
- The present invention relates to fluid delivery systems for supplying fluids to patients and, more specifically, to a fluid delivery system including a bulk container and pump assembly suitable for delivering a fluid to a patient under pressure.
- 2. Description of Related Art
- In many medical procedures, it is desirable to inject a fluid into a patient. In certain medical procedures such as computed tomography (“CT”) and angiography, different types of contrast media (often referred to simply as contrast) are injected into a patient for diagnostic and therapeutic imaging purposes. For example, contrast media are used in diagnostic X-ray procedures such as angiography, venography, and urography, CT scanning, magnetic resonance imaging (MRI), and ultrasonic imaging. Contrast media are also used during therapeutic procedures including, for example, angioplasty and other interventional radiological procedures. Often, the medical procedure may involve the supply of intravenous drugs, replacement fluids such as saline and glucose, and the like.
- A number of problems arise in the use of current fluid delivery systems and methods for injecting fluid into a patient's body. For example, it is often difficult to accurately control the pressure and flow rate of the fluid delivered by the pumping mechanism. Although peristaltic pumps have long been successfully used in relatively low pressure applications, peristaltic pumps are difficult to control with accuracy.
- In the case of relatively higher pressure applications, such as CT and angiography, mechanized syringe injectors are used. The use of mechanized syringe injectors also results in a number of drawbacks. Current mechanisms for powering and controlling syringe pumps are complicated, inefficient, and costly. Expensive and bulky pressure jackets for housing the syringe pumps are often required to prevent failure at high pressures. Syringe pumps are severely limited in that only the volume of fluid contained in the syringe may be injected at one time. Disposable syringe pumps are costly. Moreover, the rise time of syringe injectors is limited by the inertia of the extensive drive train required to translate motor rotation into syringe plunger motion.
- These and other drawbacks in current syringe pumping systems create and magnify a number of inefficiencies in current procedures for injecting contrast media. For example, a number of factors, including, but not limited to, the procedure to be performed and the size of the patient, determine: (i) the contrast to be used, (ii) the concentration thereof, and (iii) the amount to be injected. Under current practice of injecting contrast media via syringe pumping systems, hospitals must purchase and stock many contrast media concentrations in multiple container sizes in an attempt to provide the correct concentration and amount of a specific contrast for a specific procedure, while minimizing the wastage of expensive contrast. This is likewise the case with more routinely used fluids, such as saline or glucose concentrations, used in hospital or other patient-care settings.
- Thus, most contrast media are provided by manufacturers in numerous concentrations in sterilized containers (such as glass bottles or plastic packages) ranging incrementally in size from 20 ml to 200 ml. The contrast is generally aspirated from such containers via the syringe pump used to inject the contrast, and any contrast remaining in the container is discarded to prevent infection with potentially contaminated contrast. The hospital staff is faced with the task of choosing an appropriately sized contrast container to assure an optimum study while minimizing discarded contrast. Time-consuming procedures are required to reload the syringe if more contrast is required than originally calculated. The inventory of contrast containers required under the current system increases costs and regulatory burdens throughout the contrast media supplier-consumer chain.
- Beyond the field of contrast media supplied for radiological studies and therapeutic procedures, fluids that are more routinely supplied to patients in hospital settings, such as glucose and saline concentrations, are typically provided in glass or plastic bottles or in IV bags of varying size and concentration. The contents of such containers are emptied, for example, under the force of gravity or by the attachment of a pump device to the container to inject the contents under pressure into a patient, such as may be desirable for the intravenous delivery of drugs to a patient. Such extra pump devices are typically complicated, costly, and bulky devices that require significant up-front capital expenditures and require some degree of expertise on part of the medical practitioner charged with setting-up and priming the pump device. The time spent configuring such pump devices to operate properly takes away from the care time that may be administered to a patient in a hospital or other patient care setting. An intent of the invention described herein is to provide a low cost and user-friendly alternative to such pump devices and a fluid delivery system that may be generally used for many different fluid delivery procedures.
- In one aspect, the invention is directed to a bulk container and pump assembly generally comprising a container body comprising a generally closed end and defining an opening leading to an interior chamber within the container body for holding a medical fluid, and a pump device closing and sealing the opening in the container body and adapted to draw the medical fluid from the container body and deliver the medical fluid to a patient. The container body may be substantially rigid, or take the form of containers with soft sides and pliable containers such as IV bags each with an appropriate opening for receiving the pump device. The container body and pump device may be conveniently disposable as a singular unit.
- In one form, the pump device may be a gear pump. Such a gear pump may be disposed in a housing sealing the opening in the container body and comprise spur gears. The spur gears may be disposed in the housing sealing the opening in the container body.

- The pump device may comprise a housing sealing the opening in the container body, with the interior of the housing in fluid communication with the interior chamber defined by the container body. The housing may comprise a valve for dispensing the medical fluid from the container body via the housing to the patient. A plunger may be disposed in the container body for dispensing the medical fluid from the container body, for example, upon actuation of the pump device.
- An encoding device may be associated with the container body. The encoding device may be operable to provide container body information to a sensor. The encoding device may be an optically or mechanically readable device. The container body information may include, but is not limited to, container body volume information and the type of medical fluid contained in the container body.
- A drive device may be operatively connected to the pump device for driving the pump device. As indicated, in one form, the pump device may be a gear pump and the drive device may be adapted to drive the gear pump. The gear pump may comprise spur gears and the drive device may include a motor coupled to the spur gears for driving the spur gears.
- A fluid level sensor may be associated with the container body for determining the level of medical fluid in the container body. Such a fluid level sensor may be adapted to sense when the medical fluid reaches a minimum level in the container body.
- The bulk container and pump assembly may be releasably lockable to a base supporting the drive device adapted to drive the pump device. The bulk container and pump assembly may be releasably lockable to the base with one or more releasable clamps. A sensor may be associated with the releasable clamp. Such a sensor may be adapted to identify a locked position of the releasable clamp.
- In another embodiment, the fluid delivery system generally comprises a control unit, a drive device operatively controlled by the control unit, and a bulk container and pump assembly. As in previous embodiments, the assembly includes a container body comprising a generally closed end and defining an opening leading to an interior chamber within the container body for holding a medical fluid, and a pump device closing and sealing the opening in the container body and adapted to draw the medical fluid from the container body and deliver the medical fluid to the patient.

- An encoding device may be associated with the container body. The encoding device may be operable to provide container body information to a sensor operatively connected to the control device. In form, encoding device may be an optically readable device.
- A further aspect of the invention relates to a method of supplying a medical fluid to a fluid delivery system, generally comprising providing a bulk container and pump assembly, and releasably associating the bulk container and pump assembly with a drive device for driving a pump device of the assembly.

- Other aspects of the method may include releasably locking the bulk container and pump assembly to a base supporting the drive device, and sensing a locked state of the bulk container and pump assembly with the base.
- In the method, actuation of the drive device may drive the pump device of the bulk container and pump assembly to draw the medical fluid from the container body.

However, it is to be understood that the embodiments described hereinafter may assume many alternative variations and configurations. It is also to be understood that the specific devices illustrated in the accompanying drawing figures and described herein are simply exemplary to the invention and should not be considered as limiting.
- One aspect of the invention is directed to a bulk container and pump assembly. Another aspect of the invention incorporates the bulk container and pump assembly as part of a fluid delivery system. In the system, a pump draws fluid from a bulk container and then delivers the fluid to a patient through an appropriate interface device such as a catheter, IV needle, and/or tubing set. The system may be adapted to supply a relatively small volume of fluid to a patient allowing the system to be used as a drug infusion, gene therapy, or chemotherapy vehicle, or a larger volume of fluid such as contrast media typically used during computed tomography (“CT”) and angiographic or other cardiovascular procedures. The bulk container and pump assembly is desirably constructed as a composite device from relatively inexpensive materials. This advantageously allows the bulk container and pump assembly to be disposed of as a singular unit after a single use thereby increasing patient turn around time due to less user interface with the fluid delivery system, and decreasing the possibility of system and medical fluid contamination.
- With reference to
FIGS. 1 and 2 , a bulk container and pump assembly, denoted generally as reference numeral 2 (hereinafter “assembly 2”), generally comprises acontainer body 4 and apump device 6.Container body 4 defines a substantially closedtop end 8 defining anopening 9, and further defines abottom opening 10 leading to aninterior chamber 12 defined withincontainer body 4 for holding a medical fluid. The medical fluid may be contrast medium for use in medical imaging applications, a fluid for use in drug infusions, a fluid for use in gene therapy or chemotherapy, or a general medical fluid used in hospital or other patient care settings such as saline and glucose IV's.Container body 4 is substantially rigid and may include, but is not limited to, rigid containers, containers with soft sides, and pliable containers such as IV bags. -
Container body 4 also includes aplunger 13 positioned withininterior chamber 12. As indicated,opening 9 is defined in generallyclosed end 8.Opening 9 allows for the creation of a pressure differential withininterior chamber 12 used to empty the fluid frominterior chamber 12 as will be discussed in further detail hereinafter. Instead of anopening 9 in theclosed end 8 ofcontainer body 4, a check valve or other structure that allows air, but not liquid to pass intointerior chamber 12 may be utilized.Plunger 13 includes aplunger stem 60 which extends throughopening 9 in a pre-use state ofassembly 2. Aplunger locking clip 62 is positioned overopening 9 and in engagement with plunger stem 60 extending fromplunger 13 to secure theplunger stem 60 in place withinopening 9.Plunger stem 60 extends throughopening 9 in a pre-use state ofassembly 2 to prevent displacement ofplunger 13 before use and, further, desirably to sealopening 9 prior to use. Therefore, plunger stem 60 may operate as a plug foropening 9 in the pre-use state ofassembly 2 and may be held in place by engagement of theplunger locking clip 62 withside grooves 64 defined in theplunger stem 60. If desired, anend cap 66 may be disposed at the end of plunger stem 60 to secure the disposition of plunger stem 60 inopening 9 and prevent the accidental dislodgement ofplunger locking clip 62 from theplunger stem 60.Plunger stem 60,plunger locking clip 62, andend cap 66 operate as a removable sealing structure which allows theinterior chamber 12 ofcontainer body 4 to be vented to atmospheric pressure and thereby allowpump device 6 to empty the contents of thecontainer body 4 when actuated. -
Pump device 6 generally closes and seals opening 10 incontainer body 4 and is adapted to draw fluid fromcontainer body 4 and deliver the fluid to a patient.Pump device 6 includes anupper housing body 14 and alower housing body 16 generally forming apump housing 18.Pump housing 18 is secured tocontainer body 4 desirably via a snap-fit connection thereby sealing bottom opening 10 incontainer body 4. The interior ofpump housing 18 is in fluid communication withinterior chamber 12 defined bycontainer body 4 via adischarge opening 19 inupper housing body 14 which is further configured for at least partial insertion into bottom opening 10 incontainer body 4, as discussed herein. In order to ensure that a fluid tight seal is provided between bottom opening 10 andupper housing body 14, aperimeter seal structure 20 may be associated with theupper housing body 14. Such aperimeter seal structure 20 may extend around a centralcylindrical area 21 formed onupper housing body 14 which is adapted for insertion into bottom opening 10 defined incontainer body 4. As shown inFIG. 2 , discharge opening 19 is defined in centralcylindrical area 21.Seal structure 20 forms a seal between the interior wall ofcontainer body 4 definingbottom opening 10 and the centralcylindrical area 21. In one form, theperimeter seal structure 20 may be formed by a pair of O-rings 22 which are disposed withinperimetrical groves 24 extending around centralcylindrical area 21 ofupper housing body 14. As is known, O-rings are conventional structures that are used to seal fluid connections. Inpump housing 18, O-rings 22 form a generally fluid tight barrier between the interior wall ofcontainer body 4 definingbottom opening 10 and the centralcylindrical area 21 ofupper housing body 14 when theupper housing body 14 is secured to thecontainer body 4. - To secure the sealing of opening 10 in
container body 4 byupper housing body 14, a securing connection is established between thecontainer body 4 and pumphousing 18. For ease of assembly, such a securing connection is desirably a snap-fit connection. For this purpose,container body 4 may be formed with abottom flange 70 having dependingengagement tabs 72.Upper housing body 14 is formed with an opposing and generally cooperatingflange 74 which defines a plurality of receivingopenings 76 that are adapted to accept the dependingtabs 72 onbottom flange 70 ofcontainer body 4. The dependingengagement tabs 72 may be conventional arrow-shaped or barbed tabs which engage the receivingopenings 76 in a snap-fit manner and thereafter maintaining the engagement ofbottom flange 70 with cooperatingflange 74. -
Lower housing body 16 is a generally bowl-shaped structure with an upstanding lip or rim 78 defining an interior volume or area A in which theupper housing body 14 is secured.Lower housing body 16 includes a plurality ofinternal engagement tabs 80 which are adapted to engage a second series of receivingopenings 82 defined in cooperatingflange 74 in a similar manner tocontainer body 4 andupper housing body 14 just described. Again, theinternal engagement tabs 80 may be conventional arrow-shaped or barbed tabs which engage the receivingopenings 82 in a snap-fit manner and thereafter maintain the engagement ofupper housing body 14 withlower housing body 16. While a snap-fit connection is indicated as a means of securingcontainer body 4 toupper housing body 14 and securingupper housing body 14 tolower housing body 16, this exemplary connection technique should not to be construed as limiting the possible additional alternative methods which may be used to secure the connection ofpump housing 18 tocontainer body 4. One example of such an alternative means includes the use of an adhesive, typically a medical grade adhesive, to form a securing connection betweenbottom flange 70 oncontainer body 4 and cooperatingflange 74 ofupper housing body 14 and, analogously, to form a sealing connection between cooperatingflange 74 and the interior oflower housing body 16. In the former securing connection, an adhesive may be used to securebottom flange 70 to cooperatingflange 74. In the latter securing connection, an adhesive may be used to secure cooperatingflange 74 to the interior oflower housing body 16. Another example is the use of mechanical fasteners in place of dependingengagement tabs 72 and projectingengagement tabs 80. A further example is the use of simple mechanical clamping connections betweenbottom flange 70 and cooperatingflange 74 and between the cooperatingflange 74 and the interior oflower housing body 16. As further shown inFIG. 2 ,spacers 84 may be formed as part oflower housing body 16. Thespacers 84 are generally adapted to engage or contact the bottom interior surface of centralcylindrical area 21 formed onupper housing body 14 and stabilize the connection between theupper housing body 14 andlower housing body 16. -
Pump device 6 includes agear pump 26 enclosed withinpump housing 18 betweenupper housing body 14 andlower housing body 16.Gear pump 26 is capable of delivering accurate volumes of fluid at substantially uniform pressures without or with a minimum of pressure pulsations as is common in the syringe-type injectors discussed previously.Gear pump 26 comprises afirst spur gear 28 that drives an identical second spur gear 30. However, both the first and second spur gears 28, 30 may be driven in which case the first and second spur gears 28, 30 rotate in opposite directions. In operation, the equal and opposite motions of thefirst spur gear 28 and the second spur gear 30 creates vacuum pressure withininterior chamber 12 ofcontainer body 4 which pullsplunger 13 downward within theinterior chamber 12 thereby forcing fluid from thecontainer body 4 intopump housing 18 viadischarge opening 19 inupper housing body 14. Desirably, the first and second spur gears 28, 30 forminggear pump 26 are disposed within aninternal housing 31 formed as part oflower housing body 16 ofpump housing 18. Theinternal housing 31 is in fluid communication with theinterior chamber 12 ofcontainer body 4 viadischarge opening 19 inupper housing body 14. Asgear pump 26 operates, fluid contained ininterior chamber 12 ofcontainer body 4 is pulled throughdischarge opening 19 and intointernal housing 31. Anoutlet valve 32 is positioned onlower housing body 16 ofpump device 6 which is fluidly connected tointernal housing 31 for dispensing fluid frompump device 6 and allows the fluid drawn fromcontainer body 4 to exitassembly 2.Outlet valve 32 may be a conventional stopcock valve with a standard male or female luer end connector. - As shown in
FIG. 2 , an O-ring 33 may be provided to sealinternal housing 31 from the interior area A generally defined bylower housing body 16. The sealing O-ring 33 is positioned to seal against the bottom interior surface of centralcylindrical area 21 formed onupper housing body 14 and around discharge opening 19 therein. Onceinternal housing 31 is sealed to the centralcylindrical area 21, which will occur automatically with the securing ofupper housing body 14 tolower housing body 16, a sealed fluid path is provided from theinterior chamber 12 ofcontainer body 4 to the interior ofinternal housing 31 and, ultimately, tooutlet valve 32. - With further reference to
FIGS. 3-5 , a base interface structure orplatform 34 is adapted to support the bulk container and pumpassembly 2 and, further, supports devices that operate and monitorassembly 2. In the embodiment depicted, adrive device 36 is supported onbase 34 desirably in a convenient position belowpump device 6 ofassembly 2 for drivingpump device 6. The depicteddrive device 36 includes amotor 38, adrive train pulley 40, adrive train spindle 42, agear pump pulley 44, and adrive train belt 46.Motor 38 is operatively coupled to, and drives, drivetrain pulley 40. Drivetrain pulley 40 is operatively coupled to drivetrain spindle 42 viagear pump pulley 44 and drivetrain belt 46. The motive power produced bymotor 38 is applied to drivetrain belt 46 which is used to rotate gear pumppulley 44. Drivetrain belt 46 is tensioned betweengear pump pulley 44 and drivetrain pulley 40.Gear pump pulley 44 is coupled tofirst spur gear 28 to drive thefirst spur gear 28, which drives second spur gear 30 due to the meshed engagement of thefirst spur gear 28 with the second spur gear 30. As shown inFIG. 5 , gear pumppulley 44 may include ashaft 47 that extends through anopening 48 inbase 34 to engage thefirst spur gear 28 ofgear pump 26. In this manner, gear pumppulley 44 is automatically operatively connected to gearpump 26 whenassembly 2 is associated withbase 34. Once gear pumppulley 44 is coupled to thefirst spur gear 28 ofgear pump 26, thedrive device 36 may be actuated to drive spur gears 28, 30 ofgear pump 26 and dispense fluid fromcontainer body 4.Motor 38 may be a DC motor or any other suitable motor. The configuration ofdrive device 36 inFIGS. 3-5 is provided as an exemplary embodiment of a device which may used to drivepump device 6. Any suitable mechanically equivalent drive arrangement may be used in place of the pulley-drive belt system shown. For example, drivetrain pulley 40 may be a conventional spur gear that drives a spur gear provided in place ofgear pump pulley 44. - At least one, and desirably two, releasable clamps 49 are disposed on
base 34 for lockingassembly 2 tobase 34 and, further, for operatively interfacingpump device 6 withdrive device 36.Clamps 49 are desirably adapted to operate in unison, either mechanically or electrically, to engageassembly 2 to secure theassembly 2 tobase 34. Aclamp position sensor 50 is positioned onbase 34 and is associated with one of theclamps 49.Clamp position sensor 50 is adapted to identify the position ofclamps 49 and, more particularly, identify when theclamps 49 are in a locked position.Clamps 49 are generally configured to engage onto and desirably at least partially overrim 78 formed onlower housing body 16. Therim 78 onlower housing body 16, as discussed previously, generally defines an interior volume or area A whereininternal housing 31 is provided which enclosesgear pump 26. Thebottom flange 70 formed oncontainer body 4 is disposed withinrim 78, andupper housing body 14 is secured to lowerhousing body 16 within interior area A. -
Clamp position sensor 50 is adapted to identify when clamps 49 are in a locked position engaging therim 78 onlower housing body 16 of pump housing 18 (and possiblylower flange 70 of container body 4) which indicates the presence of a bulk container and pumpassembly 2 onbase 34.Clamp position sensor 50 desirably sends a signal to drivedevice 36 or a control unit associated withdrive device 36 that prevents thedrive device 36 from activating unlessclamps 49 are in a locked position and, thus,assembly 2 is properly engaged with thedrive device 36.Clamp position sensor 50 may be an optical sensor, or a simple electromechanical switch that is triggered by the locking or unlocking movement of one or both ofclamps 49. An optical embodiment is shown forclamp position sensor 50 inFIGS. 3-6 . -
Base 34 also supports at least one, and desirably two,fluid level sensors 52 for determining the level of fluid incontainer body 4.Fluid level sensors 52 are particularly adapted to determine when the fluid reaches a minimum level incontainer body 4 during operation ofassembly 2. Oncefluid level sensors 52 determine that the fluid incontainer body 4 has reached a pre-identified minimum level, thefluid level sensors 52 sends an interrupt signal to drivedevice 36 or to a control unit associated with thedrive device 36 which causes thedrive device 36 to cease operation. This interrupt or stop signal thereby prevents the system from delivering air bubbles to a patient.Fluid level sensors 52 may be optical sensors, ultrasonic sensors, acoustic sensors or any other suitable sensors known in the medical field for detecting the presence of air bubbles in plastic or glass containers or medical tubing.Fluid level sensors 52 may be conveniently supported on the structure of releasable clamps 49 as illustrated. - As generally described previously,
fluid level sensors 52 and clampposition sensor 50 may be operatively connected to drivedevice 36 or to a control unit. Anexemplary control unit 100 is shown schematically inFIG. 4 and is operatively associated with thedrive device 36.Control unit 100 may be an external computer system or like device.Control unit 100 may also be used to control operation ofassembly 2 when associated withdrive device 36 by controllingdrive device 36. Desirably,control unit 100 operatesdrive device 36 in accordance with parameters associated with the size (i.e., volume) ofcontainer body 4 and, further, the specificcontents container body 4, as well as other parameters. For this purpose, one ormore encoding devices 102 are disposed on thecontainer body 4 that are read by one or morecontainer body sensors 104 which may be conveniently placed in proximity tofluid level sensors 52, for example, abovefluid level sensors 52. For example, the supporting structure forfluid level sensors 52 may additionally be used to supportcontainer body sensors 104.Container body sensors 104 are used to read theencoding devices 102 oncontainer body 4 and send a signal or signals to controlunit 100 concerning the size or contents, or both, ofassembly 2 associated withdrive device 36, or other information relating toassembly 2 as described herein. As a result,control unit 100 is able to detect both the presence ofassembly 2 onbase 34 viaclamp position sensor 50, but is also able to “read”assembly 2 to obtaininformation concerning assembly 2. This information may be used as programming inputs to thecontrol unit 100 which will thereafter direct operation of drive device 36 (or modify operation thereof) and, hence, control the discharge of fluid fromcontainer body 4. Thus, a specific fluid delivery/injection procedure or “protocol” tailored to the patient may be performed in accordance with the information detected or “read” fromcontainer body 4 and transmitted to controlunit 100. - In this instance,
encoding device 102 oncontainer body 4 is a series of indented (i.e., recessed) spacedbars 106 of varying indentation provided in thecontainer body 4.Container body 4 is desirably formed of clear or slightly opaque molded plastic material to allow the spacedbars 106 to be read by optical means. The corresponding “reading”container body sensors 104 are positioned to read spacedbars 106 when theassembly 2 is mounted tobase 34. For this purpose,base 34 may be configured so thatassembly 2 may be mounted tobase 34 in a manner such that spacedbars 104 are always properly associated withcontainer body sensors 104. For example,base 34 may be formed with an alignment groove (not shown) and thelower housing body 16 ofpump housing 18 may be formed with a depending tab (not shown) for engaging the alignment groove which will preventassembly 2 from being clamped tobase 34 in any other orientation other than a “correct” orientation, whereinencoding device 102 is aligned withcontainer body sensors 104. This configuration may be further used to assure proper operative engagement betweenpump device 6 and drivedevice 36. - Based on the foregoing, when
assembly 2 is properly mounted and clamped to base 34,pump device 6 is automatically associated withdrive device 36 andcontainer body sensors 104 may “read” theencoding devices 102 and forward a signal or signals to thecontrol unit 100.Control unit 100 desirably recognizes the presence ofassembly 2 fromclamp position sensor 50 and, further, the signals fromcontainer body sensors 104.Control unit 100 then interprets the information contained in the signals fromcontainer body sensors 104 and conducts operation of drive device 36 (or modifies operation thereof) in accordance with the control information contained in the signal(s) fromcontainer body sensors 104. Examples of information which could be encoded inencoding device 102 include dimensions (i.e., volume) of thecontainer body 4, suggested flow rate information for dispensing the contents ofcontainer body 4, and the fluid contained incontainer body 4. Other information that may be encoded in encodingdevices 102 includes manufacturing information such as lot numbers, dates, and tool cavity number. As an alternative to encodingdevices 102 being a series of indented spacedbars 106, theencoding devices 102 could also include raised surfaces corresponding to spacedbars 106 or a simple bar code. Theencoding devices 102 could also be a mechanically read device, such as a slot, hole, or projection extending fromcontainer body 4 which registers with a switch or other electromechanical structure provided in place ofsensors 104. Another alternative is to provideencoding devices 102 as optically readable devices, such as characters, dots, and other geometric shapes that may be read by an optical sensor, such assensors 104. Further, theencoding devices 102 may contain different types of information and thecontainer body sensors 104 may be separately connected to thecontrol device 100 to provide separate input signals to thecontrol device 100. Whilecontrol unit 100 is shown physically separate fromassembly 2 and drivedevice 36, thecontrol unit 100 may be physically supported bybase 34 and form a part of the overall system. Moreover, as indicated previously,fluid level sensors 52 are desirably operatively connected to controlunit 100 and the fluid level signal generated bysensors 52 may be inputs to controlunit 100.Control unit 100 may generate the interrupt signal to drivedevice 36 when a critical low level is identified byfluid level sensors 52 which causes thedrive device 36 to cease operation thereby preventing the injection of air bubbles into a patient. -
FIG. 6 shows the bulk container and pumpassembly 2 associated with apatient interface device 90. Patient interface device orsection 90 is used to connect the flow path ofassembly 2 intravenously to a patient, and may include for this purpose acatheter 92 or other device for injecting fluid intravenously into patient such as an IV needle cannula (not shown). Thepatient interface device 90 is adapted for connection tooutlet valve 32 of bulk container and pumpassembly 2. Thepatient interface device 90 may include, for example, a medicaltubing connection section 94 including a terminal ordistal end connector 96 adapted to engage aluer connector 98 oncatheter 92 and aproximal end connector 99 adapted to engage the luer connector element onoutlet valve 32 of bulk container and pumpassembly 2. A suitable catheter forcatheter 92 and a suitable medical tubing connection section forsection 94 may be found in U.S. patent application Ser. No. 60/741,146, filed Dec. 1, 2005 and entitled “Fluid Deliver System, Fluid Path, and Medical Connector for Use with the Fluid Deliver System and Fluid Path”. The disclosure of U.S. patent application Ser. No. 60/741,146 is incorporated herein by reference in its entirety. While the bulk container and pumpassembly 2 was described hereinabove as having asingle outlet valve 32 or port, a plurality ofoutlet valves 32 may be provided, if desired. - In operation, bulk container and pump
assembly 2 is positioned onbase 34 such thatpump device 6 engages withdrive device 36. Theassembly 2 is locked in place onbase 34 using releasable clamps 49.Clamp position sensor 50 sends a signal to drivedevice 36 orcontrol unit 100 when theassembly 2 is properly locked in place onbase 34 viaclamps 49. The operator then removesend cap 66 fromplunger stem 60 and removes the lockingclip 62 from theplunger stem 60. Theinterior chamber 12 ofcontainer body 4 is now vented to atmospheric pressure. Fluid pressure in thecontainer body 4 is typically sufficient to aspirate air frompatient interface section 90 onceoutlet valve 32 is opened. However,catheter 92 or an equivalent IV needle in thepatient interface section 90 is typically prepositioned within the vein or artery of a patient and, once theconnection section 92 ofpatient interface section 90 is aspirated of air, theconnection section 92 is connected to theprepositioned catheter 90. Theassembly 2 is now desirably in fluid communication with the patient's vein or artery. Thedrive device 36 may be configured to start manually, for example, by a healthcare professional pushing a start button connected to thedrive device 36, or thecontrol unit 100 may be accessed to operatedrive device 36 in a preprogrammed manner. For example, thecontrol unit 100 may include an interface device such as a touch screen for inputting fluid injection protocol information into the memory ofcontrol unit 100 and then thecontrol unit 100 may be accessed to start the injection procedure, for example, by touching a “start” button on the touch screen. Another interface device that may be provided is a handheld controller that starts thedrive device 36 either directly or through inputs provided to thecontrol device 100. Such a handheld controller may be adapted to control operation ofcontrol device 100 to control the fluid flow fromcontainer body 4. - Once
drive device 36 is actuated, thedrive device 36 drives spurgears 28, 30 ofgear pump 26. The equal and opposite motions of spur gears 28, 30 creates vacuum pressure in theinterior chamber 12 ofcontainer body 4 thereby pullingplunger 13 downward ininterior chamber 12. The fluid incontainer body 4 is displaced intopump housing 18 and, in particular, into theinternal chamber 31 in thelower housing body 16, and then throughoutlet valve 32 to thepatient interface device 90 thereby delivering the fluid intravenously to a patient. Oncefluid level sensors 52 determine that the fluid has reached a minimum level incontainer body 4, thesesensors 52 send a cut-off or interrupt signal to drivedevice 36 orcontrol unit 100. This signal or signals stops drive device 36 (either directly or through control unit 100), thereby preventing the injection of air bubbles into the patient. The attending healthcare professional may also stop thedrive device 36 at any time using a handheld controller (not shown), if desired or by touching an appropriate “stop” button on a touch screen associated withcontrol unit 100. Once the delivery of a fluid has stopped, the releasable clamps 48 may be released and the bulk container and pumpassembly 2 is removed frombase 34 and discarded as a singular unit. Thebase 34 and drivedevice 36 having remained fluid-isolated fromassembly 2 may accept anew prefilled assembly 2 for use with another patient without fear of contamination to the new patient. - While the present invention was described by way of a detailed description of several embodiments of a fluid delivery system including one or more embodiments of a bulk container and pump assembly, those skilled in the art may make modifications and alterations to this invention without departing from the scope and spirit of the invention. Accordingly, the foregoing description is intended to be illustrative rather than restrictive. The invention described hereinabove is defined by the appended claims, and all changes to the invention that fall within the meaning and the range of equivalency of the claims are embraced within their scope.
